integration

space efficiency

low power consumption

global compliance

Integration reduces space,

power and cost

The ModemModule inte

grates

the controller, data

pump and

data access arrangement (DAA)

in one module. This integration

requires low power, low real

estate, and provides an overall

reduction in costs.

Reduces development time

The ModemModule can make your device

communication and/or Internet-ready without

requiring signiﬁcant hardware

changes to its design.

The ModemModule actually provides faster time-to-market

because it relieves

the burden and expense of writing Internet application and modem controller

code. The complete, ready-to-integrate modem module allows you to enhance

your product while you focus on developing the device’s core features.

Real-time data transfer

By adding the Multi-Tech ModemModule to any system application, you will

achieve real-time data transfers at the fastest analog modem speeds. For

data communications, the industry-standard V.92 model downloads at 56K

speeds. If needed, the ModemModule will negotiate slower speed connections

automatically. For fax applications, it supports the new industry-standard

V.34 (Super G3 fax with speeds up to 33.6K bps) or V.17 (14.4K bps) faxing

using Class 1 or Class 2 commands.

Internet-enable any device

ModemModule IP embeds Internet protocols inside any device allowing

it to send and receive data over the Internet without connecting to a PC

or gateway server. It can also serve a single web page in response to a web

browser request.

Industry-standard modem commands

The ModemModule provides industry-standard AT-style commands for ease

integration into your existing software applications. In addition, it also

provides

industry-standard error correction and data compression to shorten

transfer time and ensure data is sent error-free.

ModemModule Pin-Out

The ModemModule interfaces

easily with

existing products

through a standard serial

communication channel. The

complete

on-board DAA

interfaces with an RJ-11 jack

for direct connection to the

public switched telephone

network. The ModemModule

provides an

audio circuit

output for audio

call-progress

monitoring, and the data/fax

ModemModule features LED

driver outputs for visual

monitoring of Carrier Detect,

Transmit Data, Receive

Data and DTR signals.

The

ModemModule is a Data

Terminal Equipment (DTE) device with a

TTL serial or parallel interface

and asynchronous protocol support. The serial DTE channel

is capable of

transfer speeds to 230.4K bps and can be interfaced directly to a UART

or microcontroller.

Advanced set-up and control features

The ModemModule has several advanced features built into the design. It

supports remote conﬁguration which means you can have central site setup

and control of the remote modem modules. In addition, the modules provide

three-number storage for automatic dialing capabilities and non-volatile

memory (NoVRAM) to store user proﬁles.

Global compliance

The ModemModule has successfully completed international compliance

testing (homologation) for global approval. This means you

can specify one

module for your design without having to inte

grate speciﬁc country approved

modules for each system used across the world.

Firmware upgrades

The ModemModule also features flash memory so you can update ﬁrmware

with the latest enhancements Multi-Tech has to offer.

Developer’s kit

The ModemModule Developer’s Kit allows you to plug in the ModemModule

and use it for testing, programming and evaluation. The kit includes one

development board with RS-232 DB-25 connector, wall power adaptor, RJ-11

jack and RS-232 cable.

what’s it for?

who’s Multi-Tech?
